I am afraid my knowledge doesn’t compare to Sam2, Halevi and PAA,but I once heard a shiur from somebody who wanted to prove that the Rambam did have the Zohar. It seems to be quite a controversial issue! The Rambam when he brings down the Ikkrim, he says that anybody who believes that any statement in the ???? is superflous is oiver on an ikker, and brings a specific example which seems very random, yet the ???? on that ???? is ????? to explain how ????? ????? exist in every ???? including that very one.
He said this Bshem R’ Moshhe Shapiro
